Question Random Computer Crashes / Resets?

Jan 30, 2021
So I recently upgraded to a RTX 3070 from a 1660 ti. Ever since then I have been having random crashes that sometimes occur when playing games, attending Zoom meetings, or even while my computer is casually idiling. Sometimes the crash happens and the PC restarts, sometimes it full crashes and i cant force pc to turn off through power button i have to use the PSU switch. In event viewer this is being logged as a Kernel Power issue. The first time i noticed this I replaced my 600w 80+ bronze with a 750w 80+ gold. The problem is still occurring at basically the same rate. Anyone have any ideas on how to fix this?

Things I have tried:

1) Replacing old PSU

2) Replacing old Ram (2 occurrences of crashes where my mobo had a solid orange light meaning ram failure)

3) Reinstalling and updating every driver

4) Updating Bios

5) Lowering Power Usage on the GPU itself

6) Monitoring Temps (both CPU and GPU temps are fine)

7) DISM.exe /Online /Cleanup-Image /RestoreHealth

8) Checking the health of my ssd through Samsung Magician (its healthy)

9) Changing ram profile to allow overclocking ram to speed of 3200, then reverting it back to 2133 because it still happened

10) DISM.exe /Online /Cleanup-image /Restorehealth
